EK CHAIN 525MVXZ2 QX - Ring 525 Universal ChainRef : EKC02954A / 1147821013

EK 525MVXZ2 QX-Ring 525 (manufacturer part number: 525MVXZ2-STL 106 MLJ) — a robust transmission chain designed for both the road and occasional off-road use. Developed by EK CHAIN, this 525 QX-ring chain combines open side plates, large diameter pins, and QX seals to minimize friction between links and preserve internal lubrication.

• Type: 525 QX-ring chain
• Number of links: 106
• Color: steel / steel
• Pitch: 525
• Weight: 1.89 kg (for 100 links)
• Service life index (relative): 3500

Ideal as a replacement for a wide range of motorcycles — roadster, trail/adventure, touring, sport, vintage, or light enduro — the 525MVXZ2 is aimed at riders looking for a compact, stable, and easy-to-maintain chain. The open plates reduce weight without sacrificing rigidity, while the QX seals help to decrease friction losses and slow down internal wear.

Compatible with setups requiring a 525 pitch and 106 links, it is suitable for recent models such as KTM 1390 SUPER DUKE R EVO, DUCATI DIAVEL V4, and HONDA NT 1100 (check exact compatibility based on chain/sprocket ratio and length). Proper installation, adjustment, and regular lubrication are essential to get the best performance from the chain.
